目的总结炎性肌纤维母细胞瘤的生物学特性，提高对该疾病的综合治疗水平。 方法分析1例来源于结肠术后4个月复发的炎性肌纤维母细胞瘤病例的诊治过程并复习文献。 结果结肠来源的炎性肌纤维母细胞瘤是一种较少见的疾病，单纯手术切除存在复发可能。本例患者结合药物治疗，随访6个月，残余肿瘤大小无明显变化。 结论结肠炎性肌纤维母细胞瘤手术切除后，需结合肿瘤的病理分型及免疫组化结果，选择合适的辅助治疗方式，并定期密切随访。
ObjectiveTo improve the diagnosis and treatment of the disease, the clinical symptoms, pathological features, diagnosis and differential diagnosis, treatment and prognosis of massive lung inflammatory myofibroblastic tumor (IMT) were analyzed.MethodsA case, admitted to the Department of Respiratory and Critical Care Medicine of Xiangya Hospital, Central South University, diagnosed as massive lung IMT, was retrospectively analyzed. His clinical and chest radiological data were collected and literature which searched through CNKI, WanFang Med online and PubMed on this subject were reviewed.ResultsThe patient, middle-age male, was presented with cough, dyspnea and weight loss, whose chest radiology was characterized by a large thoracic cavity occupation. He was confirmed with massive lung IMT by several lung biopsy. From above databases, 8 cases were retrieved, including 6 articles in English and 2 articles in Chinese. In 9 cases of massive lung IMT, there were 4 males and 5 females. The age was from 1.5 to 75 years old and the average age was 28 years old. The clinical symptoms were non-specific, and chest imaging was characterized by a large thoracic occupation. One case had distant metastases with bone, adrenal gland and lymph node, and one case had distant metastasis with brain after complete surgery.ConclusionsLung massive IMT has no characteristic clinical and radiological features. And a definite diagnosis depends on pathological biopsy and immunohistochemical analysis. It needs to be differentiated from other thoracic giant tumors. The preferred treatment is complete surgical resection. The prognosis after complete resection is usually good, and probably affected by size.
ObjectiveTo explore the clinical characteristics, diagnosis and treatment of thoracic inflammatory myofibroblastic tumor.MethodsThe clinical data, pathological features, treatment and prognosis from 10 patients with thoracic inflammatory myofibroblastic tumor confirmed by pathology were analysed retrospectively from April 2012 to April 2019 at Jiangsu Province Hospital (The First Affiliated Hospital of Nanjing Medical University).ResultsTen participants including six males and four females with a mean age of 37.9 years old. Lesions were detected by physical examination in five patients, cough, chest pain and hemoptysis were the common symptoms. A total of 10 lesions including six in the right lung, three in the left lung and one in the mediastinum. Nine patients were treated with surgery, and one patient received high-frequency electrocautery though rigid bronchoscopy under general anesthesia. All the patients were confirmed by immunohistochemistry, positive rate of smooth muscle actin was 70%, positive rate of anaplastic lymphoma kinase was 70%. The mean follow-up time was 35.9 months, and one patient relapsed the other nine patients were cured.ConclusionsInflammatory myofibroblastic tumor is potentially malignant or low malignant, the clinical manifestations and imaging findings are not specific, once confirmed by pathology, radical surgery is the first choice. For the lesion limited to the airway, interventional therapy could be the choice, but close follow up is needed.
Anterior mediastinal inflammatory myofibroblastoma is a rare tumor with insidious onset and easy misdiagnosis. In this report, we presented a case of anterior mediastinal inflammatory myofibroblastoma with thymoma. The mediastinal tumor was found by physical examination, and the prognosis was good after surgical treatment. For this disease, operation is an effective method for definite diagnosis and treatment, and complete excision can achieve good outcomes.
Inflammatory myofibroblastic tumor (IMT) occurring in the pancreas was rare and few clinical cases had been reported. The specificity of clinical presentation of IMT was lacked and its CT imaging manifestations were diverse. The enhanced CT images of a rare patient with IMT of the pancreas with liver metastases were presented to the readers, and the pathophysiological mechanisms associated with the CT imaging manifestations were briefly described, so as to enhance the readers’ understanding and knowledge of the CT imaging manifestations and raise the diagnostic awareness of the disease.
Inflammatory myofibroblastic tumor (IMT) involving stomach, liver, biliary tract, and peritoneal mesentery was very rare, nonspecific clinical manifestations and laboratory examination were the main reasons for the difficult preoperative diagnosis of IMT. An IMT case involving multiple systems and multiple sites of the abdomen was presented, the CT and MRI imaging signs and pathological basis of IMT were illustrated, so as to strengthen the understanding of IMT for clinicians and radiologists.
